For autoscaling the Kubernetes cluster created with kubeadm on AWS , I'm going through the cluster autoscaler there I saw master node setup.I created master node and worker node so master node is having one ASG and worker node will have one ASG .So should I deploy CA in master node alone or to worker node also we have to deploy?
Cluster autoscaler is to scale out the workers and not for masters. You just need one auto scaler in your cluster. Hope this answers your query
